Nicole 'Snooki' Polizzi is pregnant.

The former 'Jersey Shore' star and her fiancé Jionni LaValle - who already have 20-month-old son Lorenzo - will have a ''busy year'' ahead of them as they are expecting their second child this autumn, which is around the same time they are set to tie the knot.

Snooki told Us Weekly: ''Jionni and I were trying to have our second baby since November, so every month we kept taking tests, I'm due in the fall around my wedding time. Busy year!''

The couple have endured a lengthy engagement as Jionni popped the question over two years ago, but Snooki insists the baby's impending birth won't hinder her wedding plans and she wants to be in great shape for the big day.

She added: ''I can clarify that our wedding is still on, and we are madly in love with each other. We've waited long enough and cannot wait. I also want to look somewhat in shape for my wedding. So along with still being a healthy pregnant woman, I still want to be strong and fit!''

Rumours of Snooki's pregnant first circulated in February but she declined to comment and, while she has openly discussed wanting a large family, she previously said she would put off having more children until after she wed and had built her dream home.
